LAMP-FILLING ATTACHMENT FOR OIL CANS.

SPECIFICATION forming part of Letters Patent No. 311,465, dated February 3, 1885.

App ication filed November 512, 18-3.

To all whom it may concern:

Be it known that I, WILLIAM BLOOMFIELD, of San Francisco, in the county of San Francisco and State of California, have invented a new and useful Lamp-Filling Attachment for Oil-Cans, of which the following is a specification.

Referring to the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of my lamp-filling attachment for oil-cans in position. Fig. 2 is a vertical sectional view of the oil-pump, and Fig. 3 is a vertical sectional view through the suction-chamber.

Similar letters of reference are used to indicate like parts throughout the several figures.

A represents an oil-can,which is perforated to receive a suction-pipe, B, which is connected to the suction chamber B, within which is a valve, 0, the flap of which opens upwardly into the chamber B. The flap is hinged to the top of its chamber in the usual way, and a coiled spring, D, is connected to it, which passes through the chamber and is fastened to the bottom thereof, and the whole is arranged so that it can be easily removed by withdrawing the plug D, and cleaned in case the parts should become sticky or gummed.

From the top of the chamber B extends a pipe, E, which connects with the bottom of the chamber of the oil-pump Z, as shown. The pump-chamber is provided with an upper valve, F, that is attached to the pump-rod and provided with a weighted flap, and a lower valve, F, which is constructed and arranged in the same general manner as the valve Gin the chamber B. A spindle is screwed into the cross-head of the upper valve, and extends upward and out at the top of the pump-barrel, and passes through a funnel, G, connected to the cap G. The funnel G acts as a cup to prevent overflow of the oil when the pump is being operated. The pump Z is supported in a clamp, H, having at its upper and lower ends lugs H H, by whichit is attached to the can A, the lug H being passed beneath the lower edge of the can on one side, while the lug H, which projects above the can, is connected thereto by means of screws 1, as shown in Figs. 1 and 2. The

(No model.)

I clamp H is made of such length as to be readily fitted to cans of various sizes by adjusting the connecting-screws. A foot, J, extends forward from the base of the clamp, through which a screw is passed to hold the clamp and can firmly to a table or shelf.

In order to prevent evaporation orleakage of the can after it has been tapped, a ventplate, K, is placed between the top of the can and the bottom of the suction-chamber B, in which position a spiral spring, K, serves to keep the plate down upon theface of the can.

In practice a hole is made in the top of the can large enough to receive the pipe B when the apparatus is clamped to the can, as shown, and the piston of the pump operated, which draws the oil through the suction-pipe B into the suction-chamber B, and from there through the pipe E into the pump barrel or chamber, and up through the valves F Finto the spout L to the lamp. The suction-chamber B acts as an intermediate supply-chamber to keep the pumping-chamber Z always charged or primed and ready for use, as it will always furnish a suflicient head of oil to enable the pump to work without sucking, as would be liable to occur if the pumping cylinder or chamber were connected directly with the oilcan. This construction also enables the pump to be placed on the same shelf or table which supports the can, and without projecting so far above it as to be in the way, which would otherwise be the case. It will be seen that the oil is prevented from being wasted and the danger from explosions, now so incident from lamp-filling, greatly lessened.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In combination with an oil-pump for filling lamps directly from a can, the intermediate suction-chamber, B, having a- Valve, 0, said chamber being connected with the oil-can by a pipe, B, and with the pump by a pipe, E, substantially as shown and described.

2. The vent-plate K, placed between the suction-chamber B and the top of the can, and held in place by the spiral spring K, constructed and arranged to operate substantially in the manner as set forth and specified.

3. The suction-pipe and suction-chamber ber, B, and conneotingrpipes B E, substanthe oi1-pump, in combination with the oiltially as shown and described. IO pump, constructed, arranged, and operated In testimony that I claim the foregoing I substantially in the manner and for the purhave hereunto set my hand and seal.

provided with an eduction-pipe leading into 5 pose as herein set forth and specified. WILLIAM BLOOMFIELD. [L. s.]
